Application filed June 11, 1913.

To (ZZZ whom it may concern:

Be it known that 1, ROBERT D. MILLI-IOL- AND, a citizen of the United States, residing at Redlands, in the county of San Bernardino and State of California, have invented new and useful Improvements in Railway-Crossings, of which the following is a specification.

This invention relates to railway crossings, and the principal object is to provide a block to fill in an interruption in a rail prov'ded for the flange of a wheel traveling on the crossing rail.

It is also an object to provide a resiliently mounted block which may be readily knocked down by the flange of a wheel so as not to interfere with the operation thereof.

It is a further object to provide a block which will be normally supported in resilient relation to the ends of an interrupted rail to form a practically uninterrupted tread, together with means for adjusting the tension of the resilient means.

In the drawings accompanying this specification and forming therewith the application for Letters Patent: Figure 1 is a sectional view through the groove or space intermediate the abutting ends of a rail, showing the block in section. Fig. 2 is a plan view, showing the block in normal elevated position. Fig. 3 is a detail perspective of the block alone. Fig. 4: is a detail view of the recess cut in the end of the rail. Fig. 5 is a detail of a modification showing the modified block in elevation.

More specifically in the drawings, 6 designates a rail supported on a block 7 which is intersected by a second rail 8, this rail 8 being cut out on its adjacent supported ends, as shown at 9 in Fig. 4, forming a recess having a flattened. base 10 into which may be introduced one of the trunnions 11 of the filler block 12. This block 12 is of the general rectangular form shown having a tread face let in which is preferably formed a recess 15 concentric with a bore in which is introduced a cylindrical bolt 16 having a threaded upper portion, the lower portion having an eye or bore transversely therethrough in which is engaged the upper end 17 of the coiled spring 18. This spring may be inclosed within a larger sized bore 19 extending from the base 20 of the block upwardly the proper distance, or, as shown in Specification of Letters Eatent.

Patented 9, 1913.

Serial No. 773,96.

Fig. 5, the bolt may extend below the surface of the flattened base- 20 to engage with the spring 18. The lower end or" the spring 21 is preferably connected to an eye 22 which is threaded into the base the tension of this spring being regulated by means of the nut 23 which is locked in position by a loclr nut 24:.

The operation of the device will be readily understood in view of Fig. 1 in which the flange of a wheel, shown in dotted lines, is shown upon the block forcing the latter in either direction according to the direction of travel, these positions being clearly shown by dotted lines, and immediately upon the passage of the wheel the block springs back into its normal upright position which is assisted by the flattened form of the base at the end of the slot 9. The tread of the wheel travels on the adjacent diagonally disposed block 12 so that the objectionable pound and noise incident to crossing the flange gap will be effectively eliminated.

What I claim is:

1. A railroad crossing in combination with the separated ends of a rail having recessed and registering slots in said ends, of a block provided with a tread recess and a bore therethrough together with flattened trunnions pivotally mounted in said slots, and adjustable resilient means carried in said bore for maintaining said block in position to form a continuous tread intermediate the ends of said rail.

2. A railroad crossing in combination with the interrupted ends of a rail in said crossing to provide a flanged groove, said rails having slots cut in their adjacent ends, of a filler block provided with a recess and a bore therewith, said block also having a tread surface adapted to form a continuous tread between the adjacent ends of said rails, a threaded rod mounted in said here, a sprino' connecting said rod and said rail, a nut threaded to said rod and means to pivot said filler block to said rail.

In witness that 1 claim the foregoing I have hereunto subscribed my name this 28th day of May, 1913.

RQBT. D. MILLHOLLAND.
